With a red's chip and alky I ran low 12's with Nitto's.. didnt run 11's till I got more agreesive with timing. Ran mid 11's when I started pouring in the alky..
Depends on whose alky kit you use, what chip, who's tuning the car, traction, etc.. and how well the motor is leakdown wise..
Easy.. with a 1.70 should run mid 12's no sweat. Just becuase you make boost doesnt mean you make power.. with the rite chip/conditions/tuning.. some have gone way farther. Look at TTAmeasap.. Bo.. with a stock motor and a TA49 11.34
